Strange Tire Wear
#11
Really? This made me laugh. Tire rotations are intended to evenly wear all 4 tires... but I'm sure that every tire manufacturer and salesperson is just trying to pull the wool over our eyes, HAHA. But I digress....
Have you been under the car? Off-hand I am thinking that the strange wear pattern and noise could just be caused by something rubbing on that portion of the tire. There are these dinky little plastic "mud flaps", if you can call them that, mounted to the trim on the bottom of the car in front of the tires. Or there is the e-brake cables that could be rubbing. These all might sound dumb as hell, but it could be something that simple? It could also explain the noise. Especially since your rear alignment #'s are OK. Also, is the uneven wear pattern the same all of the way around the tire, or just in one area or section of the entire tire? Reason I ask is if it is equal all the way around, then it is not likely a bearing or axle misalignment. If it is only in one portion of the entire diameter then you might have runout that is causing the uneven wear.

Well 2 million miles of driving not rotating tires and just replacing one set of axles at a time has saved me considerable money, especially on front wheel drive cars. Front average use 40,000 miles, rear average 120,000 miles.. and yes I usually get 60-80,000 miles on a set of front brake pads and up to 160,000 on rears.! After close examination of the left and right rear feathering and cupping in the tread, I decided tires were experiencing cord failure, since they were perfectly balanced but were begining to be out of round, but in different bands of the tread pattern.
So, problem solved? You had 2 tires with bad cords? Maybe its possible if you hit a hard bump or pothole during one of your 2 million miles of driving? Its not likely a manufacturing defect. Also, with your car experiences you surely must have seen surface rust on exposed metal under a vehicle. That is all it is, and totally normal!
What about wear pattern and wheel runout?

Well, the cause will never be known, but since the loud "whirring whine" in the rear, and grunching in the front wheel bearing area that can be felt in the steering wheel is still there, I'll attempt to get the dealer's service technicians to find the real source of the noise. Due to a death in the family I will need to postpone the follow up on that till next month.

My 2014 is experiencing steering wheel shake and the tire dealer says my rear tire was low on air pressure. It helped some to put air in the rear but the shake is still there. I had to use spacers 5/16" to mount my american racing razor rims as the rear hub stuck out too far and the rim would not mount. I am using spacers all around. Tires are new front 255/40/18 & 275/40/18 rear. I can feel your troubles as I am chasing this issue as well.
